We have taken the time to develop an Air to Water intercooler setup which is incorporated into the intake manifold and then welded to the stock lower. Or weld on flange is designed and machined in-house. This setup uses a 12x6x3 Bell intercooler core and is rated to 600hp. As you can see, the ugly top half of your intake manifold is replaced with this beautiful hand crafted intake manifold which is now forward facing. We recommend and are using Ross Machine throttle bodies. Depending on the chassis your 5VZ is in, hood modification may be required. The height from the top of the lower intake is 7.25". This product is made to order! This product requires sending in your stock lower intake manifold.
